The PD_RGC record holds performance data indicating configuration information for a parity group. This is a multi-instance record. The following records are not generated:

  • Records for external volume groups or virtual volume groups (Copy-on- Write Snapshot, Thin Image, and Dynamic Provisioning virtual volume groups)
  • Records for parity groups without a logical device

Collection Interval

3600

Key Field

RAID_GROUP_NUMBER

Lifetime

From when the parity group is set up to when it is removed.

Fields

Field Name Description Access Type Format
CLPR_NUMBER Number of the CLPR to which the parity group has been assigned. 1, 2 string(8)
COLLECTION_TIME Time (in GMT) when the data was collected from the storage system. 1, 2 time_t
DISPLAY_DRIVE_TYPE Type of drive making up the parity group (display name).

Depending on the drive type, one of the following values is used: SAS/7.2k, SAS/10k, SAS/15k, SAS, SATA, SATA/7.2k, SCM NVMe, SSD, SSD(MLC), SSD(RI), SSD NVMe, SSD(QLC) NVMe, SSD(FMC), SSD(FMD), FMD, FMD DC2, FMD HDE, or Unknown.2, 3

 1, 2, 3, 4 string(32)
DRIVE_TYPE Type of drive making up the parity group.

Depending on the drive type, one of the following values is used: SAS/7200, SAS/10k, SAS/15k, SAS, SATA, SATA/7200, SCM NVMe, SSD SLC, SSD MLC, SSD(RI), SSD NVMe, SSD(QLC) NVMe, FMC, FMD, or Unknown.1, 2

 1, 2, 3, 4 string(16)
INPUT_RECORD_TYPE Record type identifier, which is always set to RGC. 1, 2, 3, 4 string(8)
INTERVAL Interval (in seconds) at which information is collected. 1, 2, 3, 4 ulong
POOL_ID This field cannot be used because it is reserved. -- --
RAID_GROUP_NUMBER Parity group number. 1, 2, 3, 4 string(64)
RAID_GROUP_TYPE This field cannot be used because it is reserved. -- --
RAID_LEVEL RAID level of the parity group. 1, 2, 3, 4 unsigned char
RAID_TYPE

Combination of the RAID level and HDU of the parity group:

  • ExampleRAID5(3D+1P)

Note that the following format is used for a volume split from a distributed parity group:

  • Example when the Access Type is 1 or 2

    RAID1(4D+4D)

  • Example when the Access Type is 3 or 4

    RAID1(2D+2D)x2

 1, 2, 3, 4 string(32)
RECORD_TIME Record creation time (in GMT). 1, 2, 3, 4 time_t
SLPR_NUMBER This field cannot be used because it is reserved. -- --

Notes:

  1. FMC is the value used when the drive type is FMC, FMD DC2, or FMD HDE.
  2. For VSP 5000 series SCM drives, the information depends on the storage system microcode version:
    • If the microcode version is earlier than version 90-04-04, an SCM drive is shown as an SSD drive (SSD NVMe).
    • If the microcode version is 90-04-04 or later, an SCM drive is shown as an SCM drive (SCM NVMe).
    • When the drive type is FMC, SSD(FMC) is displayed for the following storage systems: VSP F400, F600, F800, VSP G200, G400, G600, and G800. For other storage systems, FMD DC2 is displayed.
    • When the drive type is FMD, SSD(FMD) is displayed for the following storage systems: VSP F400, F600, F800, VSP G200, G400, G600, or G800. For other storage systems, FMD is displayed.
    • When the drive type is SSD(MLC) and SCSI-connected, SSD(MLC) is displayed for the following storage systems: VSP F400, F600, F800, VSP G200, G400, G600, or G800. For other storage systems, SSD is displayed.
